Unified parameter order of CreateHandle with the rest of v8 on the way. A few
Isolate::Current()s had to be introduced, which is not nice, and not every place
will win a beauty contest, but we can clean this up later easily in smaller steps.

Original commit message:
This includes:
* Adding support for saving callee-clobbered double registers in Crankshaft code.
* Adding a new "HTrapAllocationMemento" hydrogen instruction to handle AllocationSiteInfo data in crankshafted stubs.
* Adding a new "HAllocate" hydrogen instruction that can allocate raw memory from the GC in crankshafted code.
* Support for manipulation of the hole in HChange instructions for Crankshafted stubs.
* Utility routines to manually build loops and if statements containing hydrogen code.

Initial step towards separating IC (map check(s)), handler frontend
(prototype-check) and handler backend (actual handler code).
- Still need to split the map-check (IC) from rest of the prototype
chain check.
- Still need to turn different parts in own code objects and cache them
in more optimal places.

In preparation of supporting stubs that deopt and then need to push their
register-based parameters to an arguments area on the stack that gets properly
collected, add StubFailureTrampolineFrames to hold those parameters.

Original commit message:
With parallel recompilation enabled, objects made accessible by handles may
have changed between graph construction and graph optimization. Therefore
we must not assume that information on those objects remain the same between
those two phases. To police this, we forbid handle dereferencing during
graph optimization.
Exceptions to this rule are:
- Dereferencing the handle to obtain the raw location of the object. This
is safe since parallel recompilation acquires RelocationLock
- Some places that dereference the handle for a type check. These are checked
to be safe on a case-by-case basis.

Original commit message:
HCheckPrototypeMaps currently records the prototype and the holder of the
prototype chain (both ends of the chain) and assumes that the chain elements
and their maps did not change in during the entirety of Crankshaft. The actual
traversal of the prototype chain happens in Lithium at code generation.
With parallel compilation, this assumption is not longer correct.

Original commit message:
Adapt Danno's Track Allocation Info idea to fast literals. When allocating a literal array, we store an AllocationSiteInfo object right after the JSArray, with a pointer to the boilerplate object. Later, if the array transitions we check for the continued existence of the temporary AllocationSiteInfo object (has no roots). If found, we'll use it to transition the boilerplate array as well.
